Application filed October 5, 1929. Serial No. 397,570.

I invention relates to spooling or like machines and it applies more particularly in i an improved stopping mechanism adapted to stop therotationof the spool or other yarn holderswhen the spool or yarn holder has been filled to a predetermined degree.

An object of my invention is to provide lil means for stopping a spool in a spooling machine immediately upon the spool being filled to a predetermined extent, whichxcomprises .means for immediately stopping the same without applyingfriction to thethread for 1 any great length oftime before the stopping -operation occurs Heretofore variousv stopping mechanisms havelbeen devised to automatically lift the spool. from off the rotating-.means, but these -are slow-in operation" and are adapted to wear against the threaduntil a dead center is passed at which time the stopping operation occurs.

1 'Another' object of my invention is to overcome these difliculties by providing atrigger arrangement which "is adapted to be sprung 'whenthe thread on'the spool or yarn holding device reaches a predetermined distanceffrom -thecenter of the spool, and upoirreaching this andtouching the trigger arrangement the spool will be automatically lifted off of the rotating means.

Some of the objects of invention having been stated other objects will appear as the description proceeds when taken in connection with the accompanying drawings in which r Figure 1 is a side elevation of 'a conventional spool and spool rotating means'show- 1 .is adapted to be secured to a'spooler, and

other like mechanisms.

Referring more specifically to the drawings the numeral indicates a spindle rail in the conventional spooler, and this has mounted therein for rotation the spindle 11 which is a member 32.

adapted to be driven by the pulley 12 and above this pulley 12 is the broad faced pulley 13 which is enlarged at its top portion as at 1 1, and on this enlargement the conventional spool 15 is adapted to rest to be rotated:

to have theyarn wound thereon. The forked member 16consisting of the prongs 17 and 18 are adapted to be secured to the spindle rail by means of the setscrew 19, and this projects upwardly as at 20, and has secured theretc 'eo 'the'angle'iron member 21 by means of the bolts 22, and on this angle iron member the supports 23forming a part ofmy invention are adapted to be secured. by means of'thc bolt 24. This support 23 has the upwardly:

projecting lugs'25 and 26 on each side thereof, and the pin 27 mounted'in these projections 25 and 26, and on this pin 27 the member 28 is adapted to be pivotally secured,said member 28 having a projection 29 extending? downward with hole therethrough, through which the pin 27 is adapted topierce, so that the member 28 is swingably mounted on the pin 27. projecting portion 29a integral therewitlnfl This member 28 has the upwardly and to this portion 290; is securedthe member 30 which is adapted to project upwardly and inwardly to come into engagement with the yarn on the spool when the spool is filled to a predetermined degree. has the projection 31 thereonand adjustably mounted on this projection 31 is the forked member 32 which is mounted in an adjustable manner on the projection 31 by means (if the set screw 33 which fits into the slot 34 in the .85

Secured to the lower face'of the support 23' is the spring member 36 which has the elongated slot 37therein, in which the set screw 38 fits, said set screw being threadably r mounted in the support 23. This spring-36 projects upwardly and is curledas at 39 .and

beneath this curled portion 39 the member 32 is adapted to be releasably secured, which places the member 28 below the lowerface as of the spool 15. The spring member 10 is secured to thesupport 23 by means of the set screw. a1, and the other end of this sprin member 40 presses against the lower face 0 the projection 31, tending to force the mem- This member 29180 her 81 upwardly, so that when the yarn 42 on the spool 15 reaches a certain thickness it will press against the member 30 and pull the projection 32 from beneath the portion 39 and the spring 40 will throw the parts in the position shown in Figure 2 and this will raisethe spool 15 ofi of the rotating portion 1 1. The member 30 is a broad resilient member and when the yarn 42 on the spool 15 is filled to a slightly greater degree than that shown in Figure 1 the yarn will be pressing against the member 30 and this will force the member 32'from beneath the curled portion 39 of the spring member 36, and the member 28 will fly upward under the pressure of the spring 40, and this will lift the spool 15 upwardly and stop its rotation.

It is seen that by means of the screws 33 and 38 that the position of the spring member 36 and the member 32 can be adjusted so as to time the operation of this device to cause it to engage the yarn 42 at any predetermined time.

The member 23 has the slot 23a in which the bolt 24 fits, so the time of stoppage of the spool can be determined by adjusting the member 23 with relation to member 21. The angle iron member 21 has the holes 21a in which the bolts 22 are secured so the member 21 can be adjusted vertically.

In the drawings and specification I have set forth a preferred embodiment of my invention, and although specific terms are employed, they are used in ageneric and descriptive sense only, and not for purposes of limitation, the scope of the invention being set forth in the appended claims.

I claim 1. In a stopping mechanism for spoolers or like machines, a combination with a winding spindle having a. flange adapted to support a spool to rotate the said spool by frictional contact therewith, of a pivoted bell crank lever adapted to be moved through contact with the yarn wound on the spool, a trigger mechanism associated with said bell crank lever, resilient means adapted to normally press the bell crank lever upwardly,

said trigger mechanism being adapted to be released when undue pressure is applied on the upper portion of the bell crank lever by the yarn wound on the spool.

2. In a stopping mechanism for spooling machines and the like, a winding spindle having means to engage the spool to rotate the spool by frictional contact with the winding spindle, a bell crank lever having one portion thereof extending below the spool, and normally out of contact with the spool, the other end of the bell crank lever having a portion projecting into the path of the yarn as it is wound on the spool after the yarn reaches a predetermined thickness on the spool upwardly, a trigger mechanism ada.pt ed to hold the bell crank lever out of engagement with the spool, said trigger mechanism being adapted to be sprung by pressure of the yarn on the upper portion of the bell crank lever to lift the spool off of the spindle on which it rests.

3. In a stopping mechanism for spools and the like, a spindle adapted to support a spool and to rotate the spool by frictional contact with the spindle, a bell crank lever pivotally mounted at one side of the spool, said bell crank lever having a vertical portion and a horizontal portion, the horizontal portion being forked to pass on both sides of the spindle, a spring member adapted to press the horizontal portion normally upward, a trigger mechanism associated with said horizontal portion, said trigger mechanism being adapted to be sprung by pressure on the vertical portion when the yarn is wound on the spool to a predetermined thickness to cause the trigger mechanism to be sprung to raise the spool off of the spindle.

4. In a stepping mechanism for spoolers and the like, a plurality of brackets adapted to be secured to the spindle rail, a plurality of spindles mounted in said spindle rail and being adapted to frictionally engage and retate a spool on each spindle, a member secured to the said bracket, a support adapted to be secured to the member secured to the bracket, a bell crank lever-mounted on said support, one portion of thebell crank lever extending beneath the spool and normally out of contact therewith, the other portion of the bell crank lever extending upwardly and inwardly and adapted to be engaged by the yarn on the spool when the spool has been filled to a predetermined degree, a spring member adapted to press the horizontal portion of said bell crank lever normally upward, a trigger member adapted to hold the bell crank lever in horizontal position, said trigger member being adapted to be released by pressure of the yarn on the upwardly projecting portion of thebell crank lever to release the trigger member, and to cause the horizontal portion of the bell crank lever to raise the spool off of the spindle on which it normally rests and rotates.

In testimony whereof I affix my signature.
